' w 1' Be it known that I, J osnrn TOMLDISON, a

:citizen of the United States, residing at 1 Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding-Machines, of -which the following is a full, clear, and exact specification. This invention relates to that class of folding machines particularly adapted for fold- .ing' newspapers preparatory to or simultaneously with the wrapping of the same in which the folding operation is performed by the cotiperation of one or more folding deviccs with one or more pairs of folding rolls between which the knife doubles or folds the paper, such, for example, as shown in the pending application of Sandford C. Cox "for improvements in folding and wrapping machines filed May 5, 1906, Serial No. 315,389. With machines of this character it is of course obvious that the folding rolls are relatively spaced to suit the thickness of paper which is to be forced between them, and this makes it necessary to readjust this spacing of the rolls when it is desired to fold papers of difi'erent thicknesses. This readustirg operation, however, is tedious and slow and is also inaccurate because of the difficulty of adjusting the rolls of each pair for the proper respective thicknesses.

i My invention has for its object to overcome this difficulty and to provide improved and chic ient means whereby the rolls may be quickly adjusted, a further object being to provide improved means whereby a plurality of the rolls may be simultaneously adjusted the proper relative distances with respect to each other. I

\Vith a view to the attailunent of these ends and the accomplishment of certain other objects which will hereinafter appear, -the invention consists in the features of novcity which will now be described with'reference to the accompanying drawings, and more particularly pointed out in the claims.

I In the said drawings-l-Figure l is a side elevation of a part of a foldin machine equipped with this invent-ion. ig.2 .1s a detail viewhereinafter described. F1" 3 is a vertical sectional view taken on the iine 3-3, Fig. 5. Fi 4 is an enlarged detail 5 is a plan sectionon the line 55, Fig.

3. Fig. 6 is a detail perspective View of a 5!:

tion on the ine 9 9, Fig. 3. And F 10' is a detail perspective view of a yoke hereinafter described.

In illustrating the invention everything excepting that which is necwsary for an understanding of the construction and o eration of the adjusting mechanism of t e folding rolls has been omitted. F or the purposes of this invention'it. is simply necessary to understand that the paper to be folded is, according to the ordinary method,

deposited upon a table 1, havin aslot, 2, through which the paper is forced and iven its initial fold-by any suitable folding lade or knife which is partially indicated at 3,

and by which the pa r is forced down between the initial fol ing rolls 4, 5. From here the pa r is continued in its downward course, in t is particular example of a foldin machine, by the rotating action of the ro Is 4, 5, until it is received between a sec- 8i 0nd pair of rolls 6, 7. In this example,

however, the function of the roll 7 is purely that of a feed roll, which co-actin with roll. 6 serves to convey the partially f0 ded paper down across another folding roll 8, the rolls 6, 8 constituting a pair between which the paper is again forced and folded by a sec-- 0nd folding knife or blade 9, sn rted in a suitable arm or support 10, whiz: may be given 'a reciprocating motion at the proper time by any suitable mechanism or mechanism heretofore emplo ed in folding machines, well undeistoo and not necessary to be described for an understanding of this invention. To follow further along the fold-- in action itmight be said that from the rolls 6, 8 the paper is received by other means, the particular construction and .op eration of which are entirely immaterial for an understanding1 of this invention, and indeed so far as t is invention is oonlrerned, the foldin action or operation mayl cease with the charge of t e paper from the rolls 6, 8.

with an example of folding machine thus briefly described, it. is apparent that the disown. 2.".

but with lCSpcuE to the initial number of l sheets ltiIQlYCtl upon the folding table. C-onf sequently the rolls when adjusted for a 10- page paper, for example, must be readjusted when either a paper of a larger or smaller number of pages is to be folded, and this same relative or gradually increasing dis-' tance between the rolls along the line of the folding, operation must be maintained in bar are provided with nuts 36, which prethe same ratio. The purpose of this invention is to accomplish this adjustment of all of the rolls concerned with the folding action and which require to be adjusted, simultaneously and by simple means, which will now be described.

It is apparent that the ends or journals of the various rolls are mounted in boxes 1t, 12, 13, 14, 15, respectively. The two boxes 11, 12 are mounted in a suitable guideway 16 formed in the main frame 17 at both sides of the machine, while the boxes 13, 14 are situated in similar guidcways l8, and the box 15 is ate-1i in a vertical guide-way 19, it beingnnderstood of course that one of these boxes is ateaeh end of each roller and the gnideways are duplicated in the .\s shown in Fig. 4. the box is formed with a cavity or recess :30, which is closed by :1 ea p ill and which receives the head 32 of a bolt 33. The box 14 of the lower pair of rolls is similarly constructed and arranged and provided with a similar bolt 3i. T hose. bolts 33, 3t pass through apertures in the rortical or upright cross-bar of a yoke shown in perspective in Fig. 10, and their outer ends on the outer side of this cross rent them from pulling through the perforations in the cross-bar. Interposed between the cross-bar and the caps 31 are springs 37, which when the crossbar is moved in the direction of the rolls at. 6 communicate the motion of the cross-bar to the boxes 1Q, 14 and through these to the rolls, thereby forcing the rolls toward their companion rolls 5, 7 with a iclding pressure, and when the crossbar is moved in the opposite direction the rolls 4, \3 will be simultaneously spaced with relation to their companion rolls 5, 7 a certain definite distance. it is oi course unnecessary to explain that the boxesat both ends of the rolls 4, i are constructed as in Fig. l,

g and one of these yokcs illustrated in Fig. 10,

side frames, all as commonly resorted to in l machinery of this character. In Fig. 1 of s and bolts being duplicated as shown in l lfl.

the drawings is shown a suitable train of gearing for imparting the necessary'rotation to the Various rolls. and from which it is apparent that the two top rolls 4-, 5 are provided, i'espective.l with pinions 2O, 21

engaging with idlers ii. :33, re pectively, and the next two roll 6. 7 are provided with pinions 24, 25 engaging also with the idlers 22, 2;), and serving to impart motion theret-g the idlers -32. :3 being in mesh with each cthe". The bottom roll 8 is provided with a pinion '31). and this receives rotation from an idler 2T meshing therewith and also'with pinion 25, and this idler 27 is iven rotation from a main gear 28 driven lrom any suitable source or part of the machine and which communicates its motion to the pinion 27 by an idler 29.

It, is of course. unnecessary to adjust both rolls of each pair. Therefore the boxes it and 13 remain at rest. at all times in the ends is also provided at the other side of the inallllllt for the boxes on that side. the springs 1. lach of the yohes appearing in Fig. 10 is formed with a shank 3b projecting from the cross-bar of th:- yoke at the mid-length of the cross-bar and arranged between the guide-ways l6. 15 close to the side frames 17 of the machine, so as not to interfere with the descent of the paper from the rolls 4. To each of these shanks 3R is'piroted one arm 39 of a bell-crank lever. tw of which are employed. one at each side of the machine contiguous to the side frame thereof. An example of these bell-cranks is shown in Fig. (3, and the connection between arm 39 of each and the shank is ellected in each in stance by a ilnh 4. Both bell cranks ..re mounted upon a rocker shaft ll extending across the machine and provided outside one of the side frames 17 with an operating haudie or lever l2. having a segment -23. proof their guideways. but the boxes 12, l-land l5 are provided with means for sliding them in their guideways and thereby ell'ecting the adjustment of their respective rolls. In Fig. 4 of the drawings shown an enlarged View of one of the boxes in vertical cross-section, and this may be taken as a sample indeed of the. construction of all three of the boxes 12, It and 15, although the particular section is that of the top box 12, but the bottom box 15 ditl'ers therefrom only in its position with respect to the perpenrided with a locking or clamping svrwv 4% for holding it at its proper position of adjustment. it is. of course, obvious that the segment .2, may be marked with graduations 4:3 if desired. to indicate the proper position of ad ustment for ditterent papers of given,

thicknes es. When the lever 42 is oscillated it will be seen. therefore, that both rollers 4 and 6 will be simultaneously adjusted with respect to their companion rolls 5 and 7. This oscillation of the lever also effects the adjustment. of the bottom roll 5, for it is seen that depending from the other arm 45 vac u. O

. arm i7, which is pivoted to the side frame 17 at it; at one end, while its other end is provided with a perhi-ration through which passes a bolt 49, similar to the bolt 33, having a head 50 like the bolt situated within the recess corresponding to recess 30, in

' the box'io, and which recess in box is closed by a cap plate 51 serving to retain the head 50 of the bolt. The lower end of the bolt at a point below the arm 47 is provided with a nut 52 serving torcunnnunicate the downward motion of the arm 47 to the bolt. and thence to the box 15. Therefore, it will be seen that when the rocker shaft 41 is rotated the arms 47 will pullthe roller 8 downward with respect to its companion 6 if the frockmg motion be in one direction, and 1f in the other direction the arms at? would lift the roller 8 through the intermediary of springs 54: interposed between the arms 47 and the cap plates 51 at both sides of the machine. shown on one side in Fig. l and on the other side in Fig. 3.

in Fig. 5 of the drawing is shown a detail relating to the means for loclrin the adjusting lever -12, the locking nut 4- iming screwthreaded upon a projection ot' a stud 56, which secured in the frame 17 and which stud serves as a shoulder for the segment 43 to be clamped against by the nut 44.
